Installation ProcedureGDL 69/69A Installation Manual Page 2-3190-00355-02 Revision E2.4.2 Remote Mount RackThe remote mount rack can be installed in a variety of locations, such as the electronics bay, behind theinstrument panel, under the seat or behind the rear baggage area. Leave sufficient clearance between theGDL 69/69A and any obstruction. Install the rack in accordance with AC43.13-2A Chapter 2 RadioInstallations. The remote mount rack should be mounted to a surface known to have sufficient structuralintegrity to withstand additional inertial forces imposed by a 1.86 pound unit (1.72 lbs. for GDL 69). If itis necessary to build a shelf or bracket to mount the GDL 69/69A rack or if is not certain that the chosenlocation is of sufficient structural integrity, refer to Appendix C. Refer to Figure 1-2 for the GDL 69/69Aremote mount rack dimensions. The rack can be mounted vertically using four 8-32 pan head screws(MS35206, AN526 or equivalent.) It can also be mounted horizontally using four 6-32 100° counter-sunkflathead screws (MS24693, AN507R or equivalent.) Ensure that the rack has a ground path to theairframe by having at least one mounting screw in contact with the airframe to minimize radiatedelectromagnetic interference (EMI).GDL 69P/N: 011-00986-00P/N: 001-00987-00GDL 69ABACK PLATE ASSEMBLYP/N: 011-00796-35CONNECTOR KIT ASSEMBLYP/N: 011-00997-00GDL 69 REMOTE MOUNT RACKP/N: 115-00658-00Figure 2-2.

This modular rack may be mounted behind the instrument panel or in the avionics bay. Referto Figure 1-3 for the GDL 69/69A G1000 modular rack dimensions. This STC covers the installation ofthe GDL 69/69A modular rack into the installed G1000 integrated avionics system rack, but does notcover the installation of the G1000 integrated avionics system rack.2.4.4 Remote SwitchesInstallation of rocker switches should be made on a flat surface and located at a convenient locationwithin the cabin. Each rocker switch installed must be properly marked of its function. Use of rockerswitches vs. toggle switches will prevent the possibility of raising and lowering the volume at the sametime or raising and lowering the channels at the same time. Wire used for discrete switches should be 24AWG (MIL Spec M22759) and should be routed as appropriate, avoiding kinking or sharp bends. Figure2-3 shows typical rocker switches.
